•
power supply modules do not take up I/O image space if
placed in the higher numbered slots in the chassis. The adapter
will scan I/O space from the leftmost slot to the rightmost slot,
so any power supply modules or nondiscrete modules are used
most efficiently if placed in the right side of the chassis.
•
ATTENTION: It is possible to have only 1/2 of a 32-point
I/O module function since you can configure the map table to
a single word (16-bits), when a 32-point module requires 2
words.
